Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I think the first line of diagnosis would be to see whether the problem is on the client or on the server, and whether it is in sending or receiving. An easy check is to see whether the DHCP server is reporting requests from your host, and whether it is saying it responds to the requests. This can probably be determined by looking in the server's system log files, probably /var/log/messages. If you don't have access to this, then I suggest setting up a temporary server on an isolated network to perform some testing.
I have not used udhcpc; I assume it is not part of the ISC DHCP package. Perhaps try using the ISC DHCP client, which provide the dhclient tool.
What exactly do you mean by 'our app will run it'? In my experience, most dhcp clients are run as a daemon process.
